AUTOMATIC GAS-LIGHT EXTINGUISHE R.

SPECIFICATION forming part of Letters Patent No. 254,198, dated February28, 1882,

Application filed November 11, 1881.

fication.

This invention has reference to an attachment to clocks, by means ofwhich at any desired time the gas for supplying one or more burners maybe automatically turned off or on or an alarm operated.

The invention consists in providing the arbor by which the hour-hand isturned with a sleeve provided with acam and an auxiliary dial and aspring-pressed latch, constructed to release a rod operated by a springor weight and connected with one or more gas-cocks, so that at the timefor which the device-is set the gas will be either shut off or morefully turned on,

as will be described hereinafter.

Figure 1 is a view of the mechanism of a clock,showingan auxiliary dial,partly broken away to show the mechanism for operating the gas-cock moreclearly. Fig. 2 is a front and side view of the auxiliary dial, showingthe cam by which the mechanism for operating the gas-cock is operated.

.In the drawings, A represents the frame of a clock provided with theusual gears.

B is the pendulum, and Uis the arbor, to which the minute and hour handsare secured.

In clocks the minute-hand is usually secured to the end of the arbor andthe hour-hand to asleeve surrounding the arbor, both connected with thegear, so that the minute-hand makes the revolution in one hour and thehour-hand makes one revolution in twelve hours.

On the sleeve of the hour-hand I place the auxiliary dial D, providedwith the cam E, so that, while it can be turned on the sleeve of thehour-hand, it will turn with the same. The cam E supports the lever j,which is pressed against the cam by the spring 9. The end of the leverf, or a lateral'projection fromthe same, bears against a shoulder formedon the rod h, one end of which is connected by means of a rod, wire, orcord with the lever of the gaseock t', and the other end is connected inthis case with the spring is. A weight may be connected with this end,or a coiled spring may be used to operate the gas-cock when released.

(No model.)

The cam E is provided with the notch e, and when in the turning of thecam the end of the spring-pressed lever f reaches the notch e the end ofthe lever suddenly enters the notch and releases the rod h. The springor any other force, acting on the rod, moves the same and operates thegas-valve.

An alarm may be operated at a distance from the clock by this device atthe same time that the gas-cock is operated. Gas may be allowed to burnso as to give a small flame, and at a given time the gas-cock may beoperated to turn on more gas, so as to increase the light.

The operation of the device is as follows: The auxiliary dial being inplace, the notch e is on a line with figure XII. If now the auxiliarydial is so that all the figures are on radial lines with the figures onthe fixed and usual I dial, then the device will operate at twelveocloek, the figure XII being under the hourhand; If it is now desired toturn the gas oft or on at three oclock, then the auxiliary dial is moveduntil the figure III is under the hourhand, and so for any other hour.When the hour-hand reaches this hour on the fixed dial the notch a willbe under the end of the lever f and the rod It will be disengaged.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent 1. The combination,withaclock, of the auxiliary dialD, adjustablyseeured upon the hourhand sleeve and provided with thenotched flan gc E, the rod It, provided with a catch or shoulder andconnected with a gas-cock, the lever having oneend arranged to engagewith said shoulder and to rest upon the periphery of the flange E, and aspring arranged to press said lever into the notch in said flange andrelease it from said shoulder, substantially as described.

2. The combination, with a clock and the cock of a gas-burner, of anadjustable tripping device upon the sleeve of the hour-hand, a rodoperated automatically to move the gas-cock in one direction, and adevice arranged to hold said rod at a point of its movement in theopposite direction and to be disengaged therefrom at a predeterminedperiod by the action of tripping device upon the hour-hand,substantially as described.
